Android cpu memory

As a geek there is no doubt that I always want to keep a close eye on the performance of all my systems. This is especially true when I feel like something is eating up all the resources available and want to investigate it further to find the culprit. There are all kinds of tools you can use for this on a desktop OS, and if you’re running an Android device I recommend Cool Tool.

Cool Tool provides a very heavily customizable interface for monitoring things like CPU usage, memory usage, Wi-Fi signal level, and much more. Once you open up the app you’ll be presented with a lot of settings to choose from, and as soon as you hit the Show Panel button in the lower-left corner you should see a small overlay on the screen with the info you requested. This panel will lay over anything else on the screen so you’ll want to keep that in mind while adjusting the position using the on-screen directional pad.

Here is what it looks like with a lot of the various meters enabled and positioned along the top of my Nexus 7:

What can you monitor with Cool Tool? Here’s a list of the different meters and gauges available in the app:

  • CPU Usage meter
  • Free RAM meter
  • CPU Frequency indicator
  • 2G/3G/Wi-Fi Traffic meter
  • Battery Level
  • Battery Temperature
  • Battery Current (mA)
  • Wi-Fi Signal Level
  • Time/Date indicator
  • GSM Cell Signal Level
  • Number of fixed GPS satellites
  • SD Card free space
  • Most resource-intensive processes

This isn’t something that I always keep enabled on my device, but I do use it occasionally. Recently I used it to test out the different Wi-Fi channels on my router. With this I was able to keep an eye on the precise Wi-Fi signal strength throughout my house.
